3月30日，从国网浙江省电力有限公司宁波供电公司获悉，“紧凑型可再生能源电热氢联产系统模块关键技术”配套工程日前在浙江宁波正式投运。

On March 30th, it was learned from the Ningbo Power Supply Company of State Grid Zhejiang Electric Power Co., Ltd. that the supporting project for the "Compact Renewable Energy, Electricity, Heat and Hydrogen Combined Production System Module Key Technologies" has been officially put into operation in Ningbo, Zhejiang Province.

工程在保障制氢效率与安全性的同时，仅用14平方米的集装箱就装下了过去上千平方米才能铺开的制氢、储氢、氢燃料电池等设备，实现了绿氢制造技术的轻量化、紧凑化跨越。

The project not only ensures the efficiency and safety of hydrogen production, but also fits all the hydrogen production, storage, hydrogen fuel cell and other equipment that previously required an area of over a thousand square meters into a container of only 14 square meters, achieving a significant lightweight and compact leap in green hydrogen manufacturing technology.

据介绍，工程使绿氢制造能够更加适配城市周边、工业园区等存在土地资源紧张情况的分布式能源核心应用场景，显著降低了绿氢制备及利用成本。

It is introduced that this project enables green hydrogen production to better adapt to distributed energy core application scenarios such as those in urban areas and industrial parks where land resources are scarce, significantly reducing the costs of green hydrogen production and utilization.

“如果用一个词形容这项工程，那就是浓缩。”紧凑型可再生能源电热氢联产系统课题负责人、国网浙江省电力有限公司电力科学研究院博士刘敏说。该工程实现了对电极、气液分离器等制氢装置的“瘦身”，以及燃料电池的紧凑型改造。

If one word is used to describe this project, it would be "concentration". Liu Min, a doctoral student at the Electric Power Research Institute of Zhejiang Electric Power Company of State Grid and the project leader of the Compact Renewable Energy Electrothermal Hydrogen Combined Production System, said. This project has achieved the "streamlining" of hydrogen production devices such as electrodes and gas-liquid separators, as well as the compact transformation of fuel cells.

值得一提的是，虽然工程在体积上有了明显“浓缩”，但整体能量转换效率并未打折，反而有所提升。其“新能源发电—储电—电制氢—氢发电—并网”五端口高功率密度变换器，使能量转化效率达到98%以上，燃料电池热电联供效率超97%(以高热值计算)，高于95%的国际标杆值。

It is worth noting that although the engineering has significantly "shrunk" in terms of volume, the overall energy conversion efficiency has not decreased but has actually improved. Its "new energy generation - storage - hydrogen production - hydrogen power generation - grid connection" five-port high-power-density converter has enabled an energy conversion efficiency of over 98%, and the thermal-electric cogeneration efficiency of the fuel cell exceeds 97% (calculated with high calorific value), which is higher than the international benchmark value of 95%.

为应对紧凑型带来的运维空间等问题，工程采用低压高密度固态金属储氢技术，实现了氢气常压存储，从源头上大幅降低了泄漏与燃爆风险。

To address the issues such as limited operation space caused by compact design, the project adopted low-pressure high-density solid-state metal hydrogen storage technology, enabling the storage of hydrogen at normal pressure. This approach significantly reduces the risks of leakage and explosion from the very beginning.

同时，在集装箱内，工程密集部署近20个监测探头，结合项目首创的氢微泄漏预警与定位技术以及安全管控软件，联动保护响应时间仅为56毫秒，可对氢气泄漏或火灾风险进行早期预警和快速处置。

Meanwhile, within the container, nearly 20 monitoring probes were densely deployed. Combined with the project's pioneering hydrogen micro-leakage early warning and location technology as well as the safety control software, the linkage protection response time is only 56 milliseconds. This enables early warning and rapid handling of hydrogen leakage or fire risks.
